GAS-SEPARATOR Specification of Letters Patent.

Application filed July 20,

Patented Dec. 31, 1912. 1911. Serial No. 639,645.

To all whom it may concern.

Be it liIlOWll that I, LOUIS A. IloiruAN, J12, a resident of Leetonia, in the county of Columbiana and State of Ohio, have invented a' new and useful Improvement in Gas-Separators, of which the -following is a full, clear, and exact description, re'terence being had to the accompanying drawing, forming part of this specification, in which the figure is a longitudim'tl sectional view of the separator.

U1" invention relates to separators for or air and is designed to provide a cheap and ctlicient device of this character for separating heavy matter from the gas or air while passing therethrough, and in which the heavy matter is deflected out of the blanket of gas or air passing through the separator, and is deposited into a reservoir out of the path of the gas or air.

The precise nature of my invention will he best understood by reference to'the accompanying drawing which will now be described, it being premised, however that various chai'iges may be made in the details of the construction without departing from the spirit and scope of my invention as defined in the appended claims.

In the accompanying drawing, I have shown a lon itudinal section through the separator, in which the numeral 2 designates the casing of the separator. This casing is providedwitli an inlet 3 for the gas or air to be cleaned, and an outlet -l for the cleaned gas or air. The side walls 5 of the casing extend downwardly to form side walls oi a reservoir (5, tor the reception of the heavy matter which has been removed from the gas or air. llxtending downwardly between the side walls f of the casing are walls 7 and 8; and extending downwardlyfrom the top of the casino" between these walls 7 and H is a deflector or b'atlle I), the lower end of which extends below the upper end oi? the wall 7.

The inlet portion of the separator is contracted vertically as at 10, at a point -adjacent to the upper end or the deflector 9, in orderto cause the gas or air to pass this point in a relatively thin layer or blanket. The wall 7 extends downwardly and for- 'ardly,thence downwardly and rearwardly, then upwardly and forwardly, and then downwardlv. meeting the wall 8 at the lower end thereof. This wvall walls ot'-tthe receptacle or reservoir ti, and is 7 'torms the end arranged to dctlect the heavy matter in a spiral manner, so as to throw it downwardly and rearwardly to a point where the parti- ('lcs Will be beyond the intluenee of the air or gases passing through the separator.

it is a clean-out opening through one of the snte walls 5, and is arranged to permit the removal of the material 12, which is deposited on the bottom of the reservoir.

The operation is as follows: The air' or gas to be cleaned is admitted through the opening 3 and then passed through the contracted portion 10, where the velocity of the moving gas and contained particles is materially increased. The gas and particles held in suspension are thrown downwardly by means of the battle 9. The gas passes out through the space 13, between the upper end of the wall 7 and lower end of the battle 9, while the velocity given to the particles contained within the gas will throw them down wardly against the wall 7, and the helical form of this wall will throw the particles dowm 'ardly amt rearvardly under the point it, where the wall 7 meets the. wall 8, at which point the particles will be out of the path of the gas moving through the separator. The full line arrows indicate the movement of the gas or air through the separator, and the dotted arrows indicate the movement of the heavy particles in the body of the reservoir.

The advantage of my invention results from the provision of a separator for gas or air in which the heavy particles held in suspension in the gas are thrown downwardly and rcarwardly into a reservoir in front. of the gas inlet. to the separator, so as to place them at a point where they can not be pit-Iced up by the moving gas.

' I claim:

1. A separator for removing heavy matter from gas or an", comprising a casing having an inlet and an outlet for the gas to be cleaned, an inclosed chamber having a rearwardly extending pocket formed by the walls of said casing for receiving the heavy matter, and an oblique deflector within said casing extending downwardly between the mouth of the inlet and the mouth of the outlet, one of the end walls of the casing being continuous and having a portion substantially parallel with the deflector for deflecting the heavy matter downwardly and rearwardly into said pocket out of the path of the gas; substantially as described.

2. A separator for removing the heavy matter from gas or air, comprising a casing having an inlet and an outlet for the gas to be cleaned, an inclosed chamber formed by the side and end Walls of said casing for receiving the heavy. matter, and a deflector Within said casing extending at an acute angle downwardly between the mouth of the inlet and the mouth of the outlet, one of the end walls extending obliquely above the bottom of the deflector, and a rearwardly and forwardly extending curved wall torming a continuation of one of the end Walls and connected to the lower end of the other end Wall, the first mentioned end Wall and the curved continuation thereof forming a second deflector for deflecting, the heavy matter downwardly into the casing and out of the path of the gas; substantially as described.

3. A separator for removing heavy matter from gas or air, comprising a casing having an inlet and outlet for the gas to be cleaned,

an inclosed chamber formed by the Walls of said casing for receivin the heavy matter, and a deflector within said casing extending downwardly at an acute angle between the end walls or the casing and between the mouth of the inlet and the mouth of the out let to the casing for deflecting the heavymatter 'downwardlv into saidchamber the end wall of the casing at the side at which the outlet is located being approximately parallel with the deflector for a portion of its length, and a curved end wall connected to the last mentioned end Wall and forming a continuation thereof, said curved well being arranged to deflect the material downwardly and backwardly; substantially as described.

In testimony whereof, I have hereunto set my hand. 4 LOUIS A. HOFFMAN, JR.
